About Us


The doctors at Retina Centers are all Board Certified vitreous / retina specialists and retina surgeons with over seven decades of combined experience.


George S Novalis, MD established Retina Centers in 1993. Ryan K Wong, MD joined in 2015, and, most recently, Shelly T Lee, MD in 2018.


Our facilities are fully equipped with state-of-the-art-technology for diagnosis and outpatient treatment of retinal disorders. Our highly trained staff strive for excellence in care, and participate in providing consultative, diagnostic, and treatment services within one office visit, when appropriate, an important time saver for working and out-of-town patients. We have several locations through Southern Arizona.


Retina Centers began work in clinical trials in 1999, and has since participated in numerous trials to further the development of sight saving pharmaceuticals and help preserve vision.


Treatment of retinal tears and detachments, as well as diabetic retinopathy and age-related macular degeneration, constitute a major part of the practice. Services offered include detailed patient education materials, skilled multi-lingual physicians and staff, flexible computer-based scheduling, and handicap accessibility.


Our physicians and staff are highly trained and look forward to providing you with the most advanced and compassionate care possible. At Retina Centers, your vision is our mission!
